Our combined ERAS protocol allows for early pain-free ambulation postoperatively. This, in turn, speeds the overall recovery process. In addition to the ERAS protocol, we work closely with physical therapists. When time permits, preoperative assessment (prehab) by a physical therapist supports upper-extremity use, posture, and core strengthening. Patients who are admitted may see an inpatient therapist during their hospitalization. We also have guidelines for upper-body and core therapy during the postoperative period. In our experience, functional outcomes improve with preemptive therapy, restoring function before any deficit occurs. In other words, it is better to prevent a functional deficit than to treat it. Upper body and posture therapy are important for all patients undergoing breast reconstruction. When autologous reconstruction is performed with abdominal tissue, core strengthening at the appropriate time is also emphasized.
